16 Claims. (Cl. 242-124) This application is a division and continuation-in-part of the co-pending application of Samuel A. Harris and Charles A. Sinquefield, Serial No. 188,202, filed October 3, 1950, now Patent No. 2,651,478.

This invention relates to improvements in warp beam or like constructions such as are used in the textile arts, and relates more particularly to improved means for obtaining a secure connection between the disc-like head and the cylinder or barrel.

It has been a problem in this art to mount the head securely with respect to the barrel so that the head will withstand the pressures caused by the material wound on the barrel and the strains caused by handling and use.

A principal object of this invention is to provide a novel joint between the barrel and the head which will withstand the forces to which it is subjected. Several representative embodiments of the invention are illustrated and described in the annexed drawings and following specification.

The invention is characterized generally by an annular device, such as a collar or split ring, which is inserted into the bore of the barrel adjacent each end thereof, and fitted into contact therewith, means beingprovided to effect a locking connection of the annular device to the barrel. The collar or device may be in the form of a plurality of sections together constituting generally an annulus. The sections, or at least some of them, may be in the form of segments. After the collar is firmly locked to the beam barrel, the beam head may be secured to the collar by appropriate means. In certain forms of the invention, a hub is locked to the barrel, and the beam head is secured to the hub.

A warp beam shown in Figures 1 to 5 comprises a barrel generally indicated at 10, and a head generally indicated at 11, at each end of the barrel. As the construction is identical at each end of the barrel, only one end will be described. The bore of the barrel is provided with annular recesses or grooves 12 adjacent the end of the barrel which provide annular, generally radial shoulders. A circular member or collar 13, is seated in the barrel adjacent its end, and the outer periphery of the collar is provided with annular teeth, shoulders, or other projections 14, corresponding in shape to the recesses or grooves 12 formed in the bore of the barrel.

These teeth and the corresponding recesses are of sawtooth construction in cross section. The collar 13 is so positioned adjacent the end of the barrel that it is aligned with the recesses 12, so that when the collar is adjusted or positioned with respect to the barrel, the projections 14 on the periphery of the collar will enter the corresponding recesses 12 and become locked therein and against the shoulders provided by the recesses by means now to be described.

The collar 13 is formed of a plurality of sections such as segments, as best shown in Figure 5, the abutting ends 13 of the segments having threaded sockets 13", adapted to receive tapered, correspondingly threaded plugs 15. When the plugs 15 are screwed into the sockets 13" with their axes parallel to the axis of the barrel 10, the collar segments are moved radially outwardly. In the form shown, a tapered threaded plug 15 is interposed between the contiguous end faces of each pair of adjacent segments.

As shown in Figure 1, the beam head 11 is of metal, preferably aluminum alloy composition, and has a centrally disposed hub portion 16 which extends into the bore of the barrel 10 and terminates short of the point where the recesses 12 are located. The barrel may also be formed of aluminum. The hub 16 and the flanged portion of the head extending from the hub are secured to the collar 13 by means of bolts 17 which pass through the hub from its outer face and into the collar, which is threaded at 18 to receive the bolts.

In assembling the construction shown in Figures 1 to 5, the segments comprising the collar 13 may first be inserted into position within the recesses 12 in the barrel. The tapered plugs 15 will then be screwed into the collar so as to cause the portions 14 of the collar segments to be forced radially into the roots of the recesses 12 in the barrel and against the shoulders provided by the grooves, thereby securely locking the collar against movement with respect to the barrel. The hub portion 16 of the head 11 will then be inserted into the end of the barrel, and the bolts 17 will be passed through the sockets formed in the hub to engage in the threaded holes 18 in the collar 13. In this way, the head 11 will be securely locked to the barrel 10.

In the modified construction shown in Figure 6, the circular member or collar 13a is shown as provided with a smooth peripheral surface which is seated within a correspondingly shaped recess or groove 12a in the barrel 10a and in face-to-face contact with the shoulder provided by the recess. The construction is otherwise similar to that described with reference to Figures 1 to 5.

In the construction shown in Figure 7, the bore of the barrel 10b is provided with an annular recess or groove 12b, spaced from the end of the barrel. A circular member or collar assembly 13b is provided with peripheral shoulder means 13b corresponding in size and shape to the recess 12b in the barrel and the shoulder formed by the recess. As shown in Figure 8, the circular member or collar assembly 13b is formed of a plurality of sections such as segments which are moved radially outwardly by means 'of tapered plugs 15b screwed into threaded portions formed between the abutting ends of the segments.

The beam head 11b shown in Figure 7 is preferably of plywood construction, and is provided with a flanged metal hub generally indicated at 30, the hub portion 30 extending into and being seated within the bore of the collar 13b. The hub 30 is provided on its outer face with a recess 19, within which the flange 21 of a gudgeon or stud shaft 20a is seated. The flanged portion 30" of the hub 30' is spaced axially from the collar 13b and from the end of the barrel 10b, so that the head 11b may be received between the flange 30" and the end of the barrel. The whole head unit, including the hub 30, gudgeon 20a and head 11b, is securely fastened to the collar 13b, and consequently to the barrel 1012, by means of bolts 17b which pass through the flange 30" and the head 11b, and are screwed into threaded sockets 18b provided in the collar 13b.

In the modification shown in Figure 9, a barrel 10g recess 12g which receives a collar assembly generally Patented Mar. 22, 1955 designated 13g and comprising a plurality of sections such as segments. The segments are of such dimensions that they may be fitted into the recess 12g by movement radially outwardly from within the barrel bore so as to lie against the shoulder provided by the recess, leaving a clearance between the contiguous end faces of each pair of adjacent segments, the adjacent end portions of the segments then being secured by welding 15g. A head 11g may then be connected to the barrel g by inserting the head hub 16g into the barrel bore and securing the head to the barrel by screws 17g extending through the head and having threaded engagement with the collar assembly 13g.

In the construction shown in Figure 10, a barrel 1011 is formed with an annular groove or recess 12h adapted to receive a collar assembly 1311 comprising a plurality of sections, e. g. segments of such dimensions that they may be fitted into the recess 12!: by movement radially outwardly from within the barrel bore so as to lie against the shoulder provided by the recess. Means for forcing the segments radially outwardly and securing them in the recess 12h comprises a plurality of screws 15h respectively interposed between contiguous end faces of pairs of adjacent segments. Each screw is substantially chordal with respect to the associated segments and has threaded connection with a lug 15lzh formed on a segment, the head or end of the screw being in abutting contact with the end face of the adjacent segment. When the segments are to be inserted, the screws 1511 are turned so as to move their heads relatively away from the end faces of the adjacent segments, thus enabling the segments to have their contiguous end faces brought into or nearly into contact with each other. After the segments have been fitted into the groove 12h, the screws 15h are turned in the opposite direction so as to move their heads against the contiguous end faces of the adjacent segments, thereby forcing the segments into and holding them in the groove 12h. A head 1111 is formed with a hub 16/1 adapted to be inserted into the barrel bore; and screws 17h passing through the head and having threaded connection with the collar assembly 1311 may then be tightened to secure the head to the barrel.

It will be observed that in each of the disclosed embodiments of the invention the head is anchored to the barrel by means including a collar assembly comprising a set of sections of such dimensions that they may be fitted into, and locked in the associated recess in the barrel.

The constructions disclosed embody the invention in preferred forms but it is intended that the disclosure be illustrative rather than definitive, the invention being defined in the claims.
